Hi All,
I'm not sure if this thread should be in Analog or Digital but here it goes.
I'm trying to find out why the next circuit was done. It is an op amp configured as a voltage follower. The input of the op amp is an PWM and the output is connected to the control voltage of an LED driver ( to control the string current). I wonder why this is done. It is just for pure isolation?, or there are other reasons?. Thanks in advance
